氣動真空(壓力)球閥是適用于真空系統(tǒng)中接通或切斷管路中的介質流。該閥以壓縮空氣為動力,通過控制氣動元件來改變氣路方向,推動活塞齒條、齒輪的機械運動,以角行程輸出扭矩來驅動球閥作啟閉運動。閥門為直通式,靠球面密封,因而既能用在真空狀態(tài)下,也能在低壓狀態(tài)下使用,并可任意位置安裝。氣缸分為雙作用和單作用(彈簧復位),可選配反饋信號裝置及電氣閥門定位器。Pneumatic vacuum (pressure) ball valve is suitable for connecting or cutting off the medium flow in pipelines in vacuum systems. The valve is powered by compressed air and changes the direction of the air circuit by controlling the pneumatic components, driving the mechanical movement of the piston rack and gear, and outputting torque through angular stroke to drive the ball valve for opening and closing motion. The valve is a straight through type, sealed by a spherical surface, which can be used in both vacuum and low-pressure conditions, and can be installed in any position. The cylinder is divided into double acting and single acting (spring return), and can be optionally equipped with feedback signal devices and electrical valves
進口氣動高真空球閥產品特點
1、密封結構設計獨特,漏率可達到<1×10-10Pa.M3/S,改變了球閥不能滿足高真空、超高真空的現(xiàn)狀;
2、開關扭矩小,配置氣動執(zhí)行器小,工作穩(wěn)定、可靠;
3、結構緊湊,重量輕,外形簡潔、美觀;
4、該閥既能適用高真空,又能適用一定的正壓力下 使用;
5、由于球閥全通導,又能達到超高真空要求,所以 也能適用于加速器真空系統(tǒng)。
